True.
It is easier since there are a lot of theories that could sum up and provide evidence to support that an object has life than life itself.
One popular theory is the cell theory which states that all organism is made up of cells, cell that came from those pre-existing cells, and reproduce by those cells themselves.
Answer:
Arginine
Explanation:
A specific genetic code specifies a particular amino acid. One amino acid can be encoded by more than one genetic code.
When a particular amino acid is encoded by more than one genetic code, all the genetic code for that amino acid mostly share common first two bases and differ from each other in the last base. This allows the same tRNA with particular anticodon to read all the possible genetic code for that amino acid and to serve as a carrier due to wobble base pairing.
Given that code "CGG" specifies arginine, the code "CGA" should also specify "arginine" since both differ with respect to the last base only.
Answer & Explanation:
<u><em>Prokaryote</em></u>: a microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles. Prokaryotes include the bacteria and cyanobacteria.
<u><em>Characteristic of prokaryote</em></u>: lack an organized nucleus and other membrane-bound organelles. Prokaryotic DNA is found in a central part of the cell called the nucleoid. The cell wall of a prokaryote acts as an extra layer of protection, helps maintain cell shape, and prevents dehydration.
<em><u>Eukaryote</u></em>: an organism consisting of a cell or cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus. Eukaryotes include all living organisms other than the eubacteria and archaebacteria.
<u><em>Characteristic of eukaryote</em></u>: larger than prokaryotic cells and have a “true” nucleus, membrane-bound organelles, and rod-shaped chromosomes. The nucleus houses the cell's DNA and directs the synthesis of proteins and ribosomes
The answer is extracellular matrix
Extracellular matrix is a term used in biology for molecule outside the cell that has a role in structural or biochemical function. The example would be collagen and elastin, strong and elastic protein that could be found in the skin. These protein is released by a certain cell, so its location is not inside the cell and it is not cellular.
Answer:
hot and dry
Explanation:
CONTINENTAL TROPICAL AIR MASS. The source region for cT air is the desert Southwest, the high plains and Mexico with relation to the United States. The air has low dewpoints and warm to hot afternoon temperatures but with mild nighttime temperature. Skies are generally clear in cT air.
